Version 2.17 release notes

Grafana Labs is excited to announce the release of Grafana Enterprise Metrics (GEM) 2.17, which is built on top of Grafana Mimir 2.17.

GEM 2.17 inherits all the features, enhancements, and bug fixes that are in the Grafana Mimir 2.17 release. Given this, it’s best to start with the Grafana Mimir 2.17 release notes.

Features and enhancements

GEM 2.17 contains the following new features and enhancements:

Federation-frontend: With cross-cluster query federation, allow automatic retries of individual requests that return retryable errors in queries. You can configure the total number of allowed attempts in the federation.max-attempts-per-request configuration parameter.
Federation-frontend: Add HTTP client cluster validation support through the federation.proxy_targets.cluster_validation_label configuration parameter.
Federation-frontend: Add support for Prometheus remote read API request.
Federation-frontend: You can set the query-frontend.extra-propagated-headers option to specify extra headers allowed to pass through to the rest of the query path.
Gateway: Add optional HTTP load balancing to the cortex.query and cortex.distributor proxies via the [proxy].load-balancing and [proxy].load-balancing-policy configuration parameters.

Upgrade considerations

This release also inherits the upgrade considerations from the Grafana Mimir 2.17 release.

After you upgrade to GEM 2.17, upgrade your GEM plugin to the latest version. For more information about the most recent enhancements and bug fixes in the GEM plugin, see the Grafana Enterprise Metrics: Changelog.
